Specification of Letters Patent.

Application. filed March 19,1906. Serial 110.306.811.

residing at and State l of Missouri, have invented a new andusel'ul gIinprovernentin Handle-Fastening Means, oi

which the following is a specification.

Our invention is 1n the nature et an irnproved means for detachablyconnecting a i handle to a hoe, rake, gig, spade, or kindred iimplements, and it prin'iarily seeks Vto provide a means of thecharacter stated ol a sinif1 ple and econoinical construction which canhe readily applied or detached and will efi a thereof, the groove 12being the shorter one feetivcly serve its intended purpose.

Gcnerically our invention comprehends a socket having nieans forinterlocking with the handle portion cial construction on the the saniewhen secured said handle whereby littcd thereon and a speby thesocket-locking i ineans is adapted to coi'i''ierate with a threadg ed.extension on the implen'ient to be attached to ell'ect a secondarylocking olf the handle l'or holding it from working out of its primarylocking position.

ln its 'more subordinate features our invention consists in certain`details ol construei tion and combination ol' parts, all of which willbe hereinafter l'ully described, pointed out iii the append .ti claims,and illustrated in the accompanying drawings, inwhich-- Figure hoe andineans apgilied.

1 is a perspeet ve view ol a gardeni handle with our improved fastener LFig. Z is a longitudinal secf tion of the lice-shank, the l'astenerdevices,

the handle.

and the socket-engaging end ol' Fig. Cil is a cross-section on'the lline3 I5 baclovard ot the handle in the Fig. Fig. 4 is a perspective view,partly in section, oll the socket nieniber. Fig. 5 a siinilar view ofthe socket-engagin end of the handle. Fig. 6 is a detail view trates therelative positions ol one ol the socket-locking lugs and the coactinglockinggroove in the handle beloi'e the handle vis shifted by theshouldered tang 3, and Fig-7 illustrates'the said parts adjusted to thesuppleinental interlocking position. cross-section taken on the line 8 8on Fig. 2.

In the practical application of our invention .we provide a socketmember 1, of the. usual external shape, the lower end of which has alongitudinal threaded aperture 2 to receive the threaded end 30, forinedin the tang or shank 3 ol the hoe, shovel, gig, or other implenientwhich it is desired todetachably; but rigidly, attach to handle, and thesaid tang withv their lower edges in a plane which illusl throat anupwardly-i'irojecting Ihas its end extended beyond the threaded portion3() and terminates in a sinooth ringer 31 of reduced diameter whereby to`provide a shoulder 32 at the ends ol. the threaded portion of the tang,the reasons for which will presently appear.

The socket member 1 on its inner wall at one side has a pair etinwardly-projected lugs 10 1t), and on the opposite side intermediatethe lugs l() it has a single lug11, and these lugs are arranged tointerlock with a pair ol bayonet-joint.locking-grooves 12 and 13 on thelower end of the handle that extend lengthwise of the handle lroin thelower end and having its upper end niergiing' with the transversegroove-section 12, that lorins the locking-groove portion as it turnsover the single lug 11 on the socket.

The groove 13, which is the longer groove, merges with two lateralgroove portions 1S 13", adapted to turn over the two lockinglrigs 1()1t) on the socket, and the lower end ot' the handle has a centrallongitudinally-extended soeket 14, the lower "end ol'A which isreinforced by the apertnred face-plate 15, as shown.

Each ol tlic lateral or tions el: the grooves -12 and lug-receiving por-13 has at its lug or shoulder a c, and the` said portions are ol"greater width than the locking-legs on the socket, whereby when thehandle has been adjnsted to bring the socket-lt; 10 and 11 to seat inthe said socket portioi'is a slight inoveinent longitudinal plane willcause the lugs 1() and 11 to engage the lower edges olA the grooveportions 12u and 13', and thereby bring the socket-lugs below theslionlders or le a d, which thereby locks the i handle troni turningwithin the socket 1. se

Fig. 8 is a l long as the handle remains loreed outward to bring thelugs c c in position lo project beand forces it longitudinally upwardiii the socketv until the lower edges ol" the socketlugs seat on thelower edge"ot the lateral groove portions of the handle in a plane belyond the lower ends ol' the socket-lugs, and to lowA the shoulders atthe throat of such for a supplemental locking of the handle within thesocket since it holds the handle from 'being rotatedand turned with thelong grooves in alinement vv ith the socket-lugs.

To maintain the socket and handle at the supplemental lockedposition, asindicated, a

jarn-nut 4 is fitted on the threaded shank'or tang of the hoe-blade, asshown. g

To detach the handle, it is only necessary to turn back the jain-nut andto turn the handle with the socket to unscrew the socket sufficiently topermit or' shovinOf the lower end of the handle inwardly until theshonl# ders or stops on the lateral grooves are sui'iiciently below thesocket-lugs (see Fig. 6) to allow the handle to be turned with the longgrooves in line with Asaid lugs when it (the handle) can be readilypulled out.

Havingthus described our invention, what we claiin is l. A fastenerdevice of, the character described, comprising a socket having a meansfor interlocking with the handle, a threaded i 4shank adjnstably mountedin the socket hav l ing a portion adapted to engage the handle wherebyto shift it and hold it toits locked `l engagement with the socket.

2. in a 'fastener means of the charactery stated, a socket having amember for interlocking with the handle, a threaded aperture in itsouter end and a threaded implementcarrying shank movable in the socketaperture and adapted to engage and clamp the .handle whereby to iixcdlyhold it intcrlocked with the socket, as set forth. 1

8. The combinatio'ii'with thc sockethnaving a'tl'iroaded aperture in itslower end, a

handle, a socket havin g an internal lug and a handle having alongitudinal groove, a transverse groove that merges with thelongitudinal groove, and provided with shoulders at groove portions,which operation provides the month of the transverse groove;.of a

l threaded shank movable in the threaded pori tion of the socket,adapted to engage the l handle whereby to. shift it in the socket, sub-E staiitially as shown and described. ,y

l 4. -The hereiiibefore-descrihed improveinent in handle-fastener means,which coniprises in combination a socket having ja gitnd'in allocking-lng, a tl'ireaded shank movable thiongh the threaded apertureinthe socket, said shank having a reduced end and a shoulder at sachend, and a handle having a longitidiiial groove and a transverse groove-that merges with the longitudinal groove, said transverse groove havinga seat portion at the forward side, said handle also having a socket atits 'front end to receive the forward ciid of the shank and a jani-nnton the shank, all being arranged substantially as shown and desc ibedwhereby when the handle is turned so its transverse groove reecives thesocket-lng, the fitting in of the shank will shift the handle to bringthe socketlug to engage the seat in the transverse groove 'in thehandle, ior the purposes del scribed. i'

l 5. The combination with a handle having l a bayonet-groove, and asocket having a lng thread ed aperture in its lower end and a lonl tointerlock with the bayonet-groove in the l handle, said socket alsohaving a threaded aperture in its end; of a threaded shank for engagingwith said aperture and the lower end of' the handle and means forholding the l shank to its adiizsted positions, as set forth; jA l s v lNV.
